The QHY 533C is a brand new cooled colour deep sky camera with zero amp glow and low noise. It contains the Sony IMX533 back-illuminated sensor with exceptional low light capabilities. The pixels measure 3.76µm, making this camera ideal for short-medium focal length telescopes.



This camera has a two-stage TEC cooling system that brings the temperature of the sensor around -35C° below ambient for low noise imaging, even in warm climates. The dark current at -20°C is only 0.0005 electrons/pixel. In addition, QHY employs a unique thermal noise control technology to reduce CMOS sensor noise to a very low value without affecting the integrity of the raw image.

The QHY 533C employs a full anti-dew technology for both CCD sensor cover glass and the sensor chamber optical window.

The 1GB DDR3 memory buffer facilitates the download of images to the computer, especially when USB traffic is high, the writing speed of your computer is slow or occupied in other processes.

In order to avoid halos around bright stars, the QHY 533C has an AR coated optical window on both sides rather than the common IR/UV cut window. Also, the protection glass of the sensor is AR coated to maximize light transmission and minimize internal reflections. It is recommended to use a UV/IR cut filter.

Note: This camera may not be supported by The Sky X. We suggest you use alternative software for image capture.
